You are of course forgetting to include 'Alien'? Not any of the sequels or prequel, just 'Alien' which in my book is simply a top film of all time, never mind ET stuff alone. It's scary, looks great, acted amazingly and is also very thought-provoking on subjects such as meeting other life out in the universe, nature, evolution, food chain, innate intelligence etc. On so many levels is it a great film.
Actually, I never really got into the whole series of Alien films. Not that there aren't some good movies in the series, just that they never really had that much of an effect on me. I did like the recent prequel "Prometheus" but not enough to rank it up there with ET or Close Encounters.
